For the given geometric series the value of the common ratio(r) is 3, while the value of a₁ is 1.
<h3>What is geometric series?</h3>
A series of numbers whose any two consecutive numbers are always in a common ratio of that series.
Given to us
Series, 1 3 9 27 81
To find the value of the common ratio(r), we will simply find the ratio of any two consecutive numbers, therefore,

As we can see the common ratio of the given series is 3, therefore, every next number will be thrice the number before.
We need to find the value of a₁ for the given series, and as we know that a₁ is the first number of the series with which the series is starting, therefore,
a₁ = 1
Hence, for the given geometric series the value of the common ratio(r) is 3, while the value of a₁ is 1.

Answer:
D
Step-by-step explanation:
To find the y- intercept, let x = 0 in the equation
Given
f(x) = -
- 1, then
f(0) = -
- 1 = -
- 1 ← y- intercept,
(0, -
- 1 ) ← coordinates of y- intercept
23.2% of the total employees is 27,200
0.232x = 27,200
x = 27,200 / 0.232
x = 117,241 (thats rounded) <==
You would see how many times 6 goes into 30. Which is 5. so you would take 2.5 multiplied by 5. which equals 11 hours
